More than 300 people are being made to re-sit their practical driving test - following fraud allegations at an Auckland VTNZ.

Police and NZTA are looking into claims testing officers at the Highbrook branch took money in return for passing applicants, over several years.  

Five officers have been sacked for misconduct - and the branch has stopped offering tests in the meantime.

Transparency International NZ executive director Julie Haggie says they need to figure out how this was possible.
